Dark Energy

Dark energy is the mysterious force driving the accelerated expansion of the universe, a key focus of modern cosmology. Current research utilizes large-scale surveys like DESI, employing machine learning techniques such as convolutional neural networks and variational autoencoders to analyze galaxy data and reconstruct the universe's expansion history in a model-independent way. These analyses aim to constrain dark energy's properties, potentially revealing whether it's a constant cosmological constant or a more dynamic entity, and improve our understanding of the universe's evolution. The results inform the design of future surveys and refine our cosmological models.
